A Russian military transport aircraft, the Ilyushin Il-76, touched down at the San Antonio de los Baños military base in Artemisa province, near Havana, on Tuesday. This event has reignited discussions about the plane's mission and cargo, with no official confirmation available regarding its purpose or contents.
The Fidel Castro Foundation reported the landing via its Telegram channel, coinciding with the upcoming book fair where Russia is named the guest of honor. Despite this, the message clarified that the aircraft was not transporting books.
"While it wasn't carrying books, we can speculate on what it might be transporting, why, and for what purpose," the message conveyed, hinting at the lack of information concerning the cargo.
The Il-76 is known for its frequent visits to Moscow's allies, including Venezuela and Nicaragua, and has reportedly visited Cuba multiple times. Additionally, the aircraft is under U.S. sanctions.
The Fidel Castro Foundation, established by Leonid Savin in 2021 to promote scientific, cultural, and informational ties between Cuba and Russia, adds to the confusion regarding the aircraft's mission in the Caribbean nation, rather than clarifying it.
The plane is operated by Aviacon Zitotrans, identified as a "state-owned Russian airline," and is listed under sanctions by the United States, Canada, and Ukraine.
Detected landing at the San Antonio de los Baños military airfield, approximately 30 kilometers south of Havana, the aircraft is typically used for transporting heavy military equipment and personnel.
Public records indicate the plane made stops in St. Petersburg and Sochi (Russia), as well as Mauritania and the Dominican Republic.
This itinerary has raised questions about various governments' willingness to permit the transit of a sanctioned aircraft, with each authorization considered a political decision amid Western restrictions on Moscow.
The same aircraft was reportedly seen flying over Venezuela, Nicaragua, and Cuba in late October 2025, amid escalating tensions between Washington and Caracas. Shortly thereafter, a U.S. operation led to the apprehension of Nicolás Maduro, altering the regional landscape.
In this context, the current flight "followed a pattern" that American analysts link to movements preceding that capture, according to Fox News.
Geopolitical Implications and U.S. Concerns
The cargo plane's arrival occurs at a “sensitive” time for Havana, as President Donald Trump intensifies pressure on Miguel Díaz-Canel’s government.
Recently, the White House declared a national emergency concerning Cuba, labeling the regime as an “unusual and extraordinary threat” to U.S. national security. Trump also announced sanctions against any country supplying oil to the island without Washington's approval.
Military ties between Russia and Cuba are again drawing concern from the United States.
Over the past decade, Moscow has reportedly resumed defense and intelligence collaboration with Cuba, seen by Washington as a strategic risk due to its geographical proximity.
Despite details about the aircraft, its operator, route, and the political context, the central issue remains unresolved: what exactly was the Il-76 carrying?
In previous operations in Venezuela, Russian media identified this aircraft as responsible for transporting advanced air defense systems. In Cuba's case, the lack of information "fuels suspicions and fears."
